HANDGRIP on HOLDER.

application inea April 29, 1927. serial No. 187,547. Y

The invention relates to a hand grip or holder for sandpaper, tools or the like.

rfhe primary object of the invention is the provision of a grip or holder of this charac v ter, wherein sheets of sandpaper can be gripped and held or tools clamped therein for the manual manipulation of the same and in the holding of such article, as for example sandpaper the same can be properly applied to a piece of work for the reducing, smoothy ing and finishing the surface thereof and like# wise, when a tool, for examplea file, scraping blade or the likev is lheld it canbe properly manipulated with the required degree of application, without liability vof injury tothe hands of the manipulator.

A further object of the invention is to provide, in a manner as hereinafter seft forth, a device for the purpose referred to including a 2o body section and a top section removable reli-v atively to the body section, and further in-V cluding aholdfast means carried by the body section and operated in a clock-wise direction to holdfast position to provide'for expeditiously and detachably securing the said secs tions together in clamping engagement with respect to the article, such as sandpaper, tools, etc., held thereby. 4

Another obj ect of the invention is the prof vision of a grip or holder of this character, wherein the sheet of sandpaper or the like or tool when clampedv thereby will be firmly and securely held for the manual manipulation of the same in the execution of anyrequirement therefor upon apiece of work, the grip or holder being of novel form to permit the application or removal of the paper or tool with dispatch' and when applied such paper or tool will be firmly gripped and held 40 for working purposes.

A further object of the invention is the provision of a grip or holder of this 'character, wherein the construction thereof permits the user to obtain a convenient, irmand required grasp thereof for the proper manipulation of the sandpaper, tool or the like held thereby.

VA still further object of the invention is the provision of a grip or holder of this character, which is extremely simple in its construction, readily and easily adjusted for raccommodating sandpaperor the like or atool, possessing but few parts, thus relieving it from disorder, strong, durable, thoroughly reliable and eliicient in its purpose, and inexpensive to maufacture.

Withthese and other objects in view, the" invention consists in the features of construction, combination and arrangement of parts,

as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, showing thepreferred embodiment of the4 invention, and pointed out inthe claims hereunto appended. Itis to' be u'nf derstood, however, that changes, variations andmodilications may be made, without departing from the spirit Vof the invention or sacrificing any of its advantages, as come properly within the scope of the claims hereunto appended. l

in the accompanying drawing Figure l is a top plan view of the grip orl holder constructed in accordance with the invention, showing. a sheet of sandpaper clamped thereto; y v

'Figure 6 is a plan view looking toward the inner face of the bottom section ofthe grip or holder.

Figure 7 is a cross-sectional view of a modi# fied form of body section of the gripor` holder. i

Similar reference charactersindicate corresponding parts throughout the v several views in the drawing.

Referring to the drawing in detail, the grip or holderl comprises a lower main'body` lsection A and an upper removable and adjustable top section B, these being of substantially similar contour, preferably of rectangular shape and constitute the clamping ele- Y mentsor parts of the grip or holder, hereinafter more fully described. i

The upper top section B in opposite longer sides thereof is provided with grooves 10, while the upper corners 11 of said sectionl are rounded and downwardly beveled, the grooves 10l being designed to form linger channels so that the said upper top section B of the grip or holder can be iirmly grasped in the hand of a user thereof. rlhe lower body section A has suitably engaged therewith throughout its outer face a cushioning layer 12 preferably made Vfrom cork, although it can be made from any other material having inherent elasticity or yieldability. This layer 12 is'for a purposehereinafter described.

Formed centrally of the inner face of the lower body section A and extending-longitu dinallythere is a pair of oppositely disposed channels or ways 13, 14, which gradually in-` crease in width and depth from their inner to their outer ends.4 The channel 18 is of rec-V tangular cross section and the channel 14 of A'intermediate the yends thereof and disposedA crosswise or transversely of said section 1s aV 30 keeper bar 19 the same being fastened to the section and countersunk therein so that its outer face will be flush with the inner surface of the section A. u

VAnchored in the section A and also extending through the bridge bar 18, as well as projecting a substantial distance from the channelled face ofsaidsection A is a rigid post 20 provided ,with right hand threads 20.

VThe post 20 is of a length to extend into the opening 16 and is formed with a pointed lower end. The post 20 is threaded through-v out andthreadedly engages with the section A centrally thereof. Carried by thatpai't of the. post 20, which extends from the 'section A is an internally threaded tubulary sleeve 21 which provides a clamping element, and it is of less length than thatpart of said post which extends fromv the section A. The sleeve 21 is readily accessible within the opening 16, asthe latter is of much greater diameter than the sleeve. The sleeve 21 is adapted to bind against the bridge bar 18 for detachably securing the sections A and B together. The'bridge bar 18 is provided, centrally of one side edge with a notch 22 for the passage of the post 20, whereby onl the superimposing of section B upon section A, with the bridge bar 18 interposed between the sleeve 21 and the bar 19, and the sleeve shifted in a clockwise direction to engage the bar 18, it will bind and connect the bars 18 and 19 together to detachably fasten said sections A and B together.

In the use of the grip' or holder for clamping sandpaper, or the like, of the abrasive type the abrasive sheet 24 is stretched across the layer 12 throughout its outer face and then folded upwardly against the opposite longer side of the body section A and nally folded in between the inner faces of said body section A and top section B, whereupon the'latter is in a position to be secured to section A by the postf20andsleeve 21, which locks the sections A and B together so as to 'firmly secure the abrasive sheet 24 to the grip or holder, whereby the abrasive sheet 24 can be utilized for reducing, smoothing and nishing surfaces of wood, metal, stone and the like.' l

In the form of threaded -post shown in Figure 7, and referred .to at 25 it does vnot have a portion thereof anchored directly in Vthe body ofthe section A, but said post 25 isanchored to the'bar 19. The inner end'of the post 25 is upset, as at 26, and weldedto the rbar 19. The section A has its inner face,

formed with a clearance 26 for the upset inner end of the post 25, and the latter eX- tends throughand projects a substantial'dis;V stance from theb'ar 19 to` receive the sleeve 21. 'The post 25 `isprovide'd throughout Otherwise thany ask with right threads.

stated the form shownin Figure 7 is to beY completed in the same way as that` shown in Figures 1 t-o 4,

The holdfast devices for securing the barsv 18 and 19 in position are indicated at 27, 28 respectively.

n Vwin be understood that the' rationing layer 1'2'onithe body'section A Vvvillpermit the proper affecting of the abrasive sheet 24 when carried upon the gripror holder to have the same make true and proper contactwith a piece Vofv work when being reduced, smoothed or finished. Also this cushioning layer 12 will assure close contact ofthe abrasive sheet24 witliworkwhen pressure is applied to the grip or holder as willbe clearly apparent. y 'y y From the kforegoing it is thought that the construction and manner of use ofthe grip or holder will be clearly understood and therefore a more extended yexplanation has been omitted. Vhat I claim is:

. 1. In a holder of the character described, a' pair of separable members, one of the mem-v bers presenting a flat face, provided with a pair of grooves vextending longitudinally of the member from opposite ends thereof, and tapering inwardly, the other member having a flat, unbroken portion of itsvr face superposed 'over the outer end portions of the grooves with the members in assembledrelation, andmeans carried by themembers and located between the inner ends of the grooves for locking t-he members in assembled relan tion.
